[0026] Working principle and advantages of the present invention: When the aircraft air outlet nozzle molding production device is in use, the working process is as follows: like Figure 1 and Figure 3As shown, the blank to be punched is placed on the die 10 above the right end of the frame, and the fan 12 is started, so that the impeller shaft of the fan 12 drives the incomplete gear 18 to rotate through the pulley assembly 13, so that the incomplete gear 18 drives the left end of the connecting rod 20 to swing up and down through the connecting rod 1 19, and then the right end of the connecting rod 20 swings up and down. When the right end of the connecting rod 20 is at the uppermost position and starts to move downward, the teeth on the incomplete gear 18 are just completely disengaged from the gear 1 11, so that the conveyor belt 5 is not driven to rotate. At this time, the right end of the connecting rod 20 moves downward and drives the pressure rod 24 and the pressure plate 26 and the punch 25 thereon to move downward through the pin rod 27, so that the punch 25 moves to the position directly below it. The die 10 approaches and punches the blank on the die 10. When the right end of the connecting rod 20 moves down to the lowest end, the punch 25 and the die 10 punch the blank. At this time, the right end of the connecting rod 20 starts to move up again. When the punch 25 is completely above the die 10, the teeth on the incomplete gear 18 are just meshed with the gear 11, so that the incomplete gear 18 drives the corresponding roller 4 to rotate through the gear 11, and then the roller 4 drives the conveyor belt 5 to transfer and shift the die 10. When the right end of the connecting rod 20 reaches the highest point, the die 10 with the blank just installed moves to the bottom of the punch 25, realizing the automatic stamping and automatic feeding of the air outlet.

[0027] As mentioned above, when the punch 25 moves downward, Figure 2 As shown, after the ejector rod 41 on the punch 25 contacts the blank, it stretches the spring 42, and the spring 42 obtains a restoring force. After the punching, the blank presses the ejector rod 44 downward, and the ejector rod 44 stretches the spring 45, so that the spring 45 obtains a restoring force. When the punching is completed and the punch 25 is separated from the die 10, the ejector rod 41 applies downward pressure to the molded product under the restoring force of the spring 42, so as to prevent the molded product from being stuck on the punch 25. And under the restoring force of the spring 2 45, the ejector rod 2 44 lifts the molded product from the die 10, and the die 10 is driven to move under the conveying action of the conveyor belt 5, and when the lower end of the ejector rod 2 44 passes through the guide slope 8, an upward force is applied to the ejector rod 2 44, thereby ensuring that the ejector rod 2 44 lifts the molded product from the die 10, avoiding the molded product from being stuck on the die 10, realizing automatic demoulding, saving time and effort, and enabling continuous stamping processing, greatly improving production efficiency.

[0028] As described above, when the fan 12 is working, the external air is transported to the pressure storage cylinder 36 through the air pipe 14, and the filter cover 15 plays the role of filtering debris and dust. After the air pressure in the pressure storage cylinder 36 increases, the slide plate 37 moves up and compresses the spring three 38, wherein the pressure relief valve 39 plays the role of pressure relief protection to prevent the pressure inside the pressure storage cylinder 36 from being too high. In the process of the right end of the connecting rod 20 driving the pressure rod 24 and the pressure plate 26 and the punch 25 thereon to move up through the pin rod 27, when the pressure plate 26 contacts the valve stem 46, it pushes the valve stem 46 to move up, and the valve stem 46 compresses the spring four 47, so that the spring four 47 obtains a restoring force, and when the valve hole 49 is connected with the through hole 1 50 and the through hole 2 48 at the same time, the high-pressure air in the pressure storage cylinder 36 passes through the air pipe 29 and the through hole 2 4 8. The valve hole 49 and the through hole 1 50 enter the air pipe 3 30, and then enter the nozzle 1 31 and the nozzle 2 35 through the branch of the air pipe 4 32 and the air pipe 5 34, so that the airflow ejected from the nozzle 1 31 blows and cleans the forming surface of the punch 25 which is just in the highest position. At the same time, the conveyor belt 5 moves the empty die 10 just above the nozzle 2 35, and the airflow ejected from the nozzle 2 35 blows and cleans the internal forming surface of the die 10, so as to automatically clean the forming surfaces of the punch 25 and the die 10, remove metal debris and debris, reduce the wear of the punch 25 and the die 10, ensure the yield rate of the formed products, and remove the air outlet product after stamping from the left end of the conveyor belt 5. The operation is simple and convenient, and there is no need to take the parts from the stamping station, which is safe and reliable.
